Data Sheet
March 17, 2011
FN6228.4
Dual, High Speed MOSFET Driver
Features
The ISL55110 and ISL55111 are dual high speed MOSFET
drivers intended for applications requiring accurate pulse
generation and buffering. Target applications include
Ultrasound, CCD Imaging, Automotive Piezoelectric
distance sensing and clock generation circuits.
• 5V to 12V Pulse Magnitude
• High Current Drive 3.5A
• 6ns Minimum Pulse Width
• 1.5ns Rise and Fall Times, 100pF Load
• Low Skew
With a wide output voltage range and low ON-resistance,
these devices can drive a variety of resistive and capacitive
loads with fast rise and fall times, allowing high speed
operation with low skew, as required in large CCD array
imaging applications.
• 3.3V and 5V Logic Compatible
• In-Phase and Anti-Phase Outputs
• Small QFN and TSSOP Packaging
• Low Quiescent Current
The ISL55110 and ISL55111 are compatible with 3.3V and
5V logic families and incorporate tightly controlled input
thresholds to minimize the effect of input rise time on output
pulse width. The ISL55110 has a pair of in-phase drivers
while the ISL55111 has two drivers operating in antiphase.
• Pb-Free (RoHS Compliant)
Applications
• Ultrasound MOSFET Driver
• CCD Array Horizontal Driver
• Automotive Piezo Driver Applications
• Clock Driver Circuits
The ISL55110 has a power-down mode for low power
consumption during equipment standby times, making it
ideal for portable products.
The ISL55110 and ISL55111 are available in 16 Ld Exposed
pad QFN packaging and 8 Ld TSSOP. Both devices are
specified for operation over the full -40°C to +85°C
temperature range.
